About Us

Columbus T Clinic was founded on the premise to provide next level men’s health care and male hormone replacement therapy with attention to each patient’s personal situation and goals. So often we find ourselves in a stage of life where we look in the mirror and ask ourselves what happened? No matter one’s situation or goals, Columbus T Clinic can help. In addition to testosterone replacement, CTC offers personal counseling with a licensed social worker, a TRT success story himself. If you want to step up to the next level of health excellence, CTC has a certified fitness coach with a master’s degree in health and nutrition. We at CTC want to provide a comprehensive approach to men’s health and alleviate the stigma that so many men find themselves at odds with.  From TRT to ED management, from primary care to lifestyle coaching and counseling, Columbus T Clinic is a man’s one stop for all his health care needs at the touch of a button. We look forward to changing your life…

Sincerely yours,

CTC Medical Practitioner

Allan is Columbus T Clinic’s medical practitioner.  His focus is on restoring men’s lives back to homeostasis. Allan himself is a TRT success story. After losing 75 lbs and changing his overall lifestyle, he founded CTC due to the malpractice he personally experienced from other testosterone clinics.
